15 old HTML tags not supported by HTML 5

HTML 5 has brought in a new generation of web-pages and now we should move ahead and forget some past things which we used to do regularly. I am in no mood to confuse you so I will directly come to the point! HTML 5 has included a lot of new Tags which I am going to tell you soon, but first we need to stop the usage of some Old HTML Tags which no longer function in HTML 5.

<acronym> Tag

The <acronym> tag was used to define acronyms in HTML 4. An acronym can be spoken as if it were a word, example NATO, NASA, ASAP, GUI.

<applet> Tag

The <applet> tag was used to define an embedded applet. You can use the<object> Tag instead of it now!

<basefont> Tag

The <basefont> tag was used to define a default font-color, font-size, or font-family for all the text in a document. But we can use CSS for this purpose now!

<big> Tag

The <big> tag was used to make text bigger.

<center> Tag

The <center> tag was used to center align text and content. We can use CSS for this purpose now.

<dir> Tag

The <dir> tag was used to define a directory list. But we can still use the <ol> and <ul> Tags.

<font> Tag

The <font> tag was used to define font face, font size, and font color of text. It was among the most used tags in HTML 4 but we have to use CSS for this purpose now.

<frame> Tag

The <frame> tag was used to define one particular window (frame) within a frameset.

<frameset> Tag

The <frameset> tag was used to define a frameset, which organized multiple windows (frames).

Note: The Frame and Frameset tags are removed because it hinders the usability of the web-page. Also, it has negative SEO implications.

<noframes> Tag

The <noframes> tag was used to display text for browsers that do not handle frames. When frames are not supported then there is no need for noframes.

<s> Tag and <strike> Tag

The <s> and <strike> tags were used to define strike-through the text. We can still use <del> instead. Also, it can be handled using CSS.

<tt> Tag

The <tt> tag was used to define teletype text. But now we can use CSS for this purpose.

<u> Tag

The <u> tag was used to define underlined text. But now we need to use CSS.

<xmp> Tag

The <xmp> tag was used to define pre-formatted text. But we can still use the <pre> tag for this purpose.

Do let me know, if you know any more tags that do not function with HTML5. You can always try the Online HTML Editor !

    Hmm.. What about SEO on HTML5? There are a lot of HTML5 examples, but anybody using HTML5 on blogger template?

  • http://www.techfreakstuff.com Rohit Sane

    @Gojeg: HTML5 doesnt seem to have come to Blogger templates.
    Also, all the old SEO rules are still valid to HTML 5.

    center and underline still works on Some browsers now. HTML 5 is still supported by browsers.

  • http://www.techfreakstuff.com Rohit Sane

    @ramkumar: HTML 5 and HTML 4 both are supported by the current browsers. Even Center and Underline work coz they can be used with CSS or with HTML 4

    Looking forward to HTML 5 and CSS 3 becoming main stream! Websites will completely change… but this will take a few more years till everyone gets browsers to support these changes.

    Great !!! These features were non-seo-friendly if you ask me…

  • http://www.techfreakstuff.com Rohit Sane

    @Siddhu: I think it will lead to a new era in the SEO industry. Anyways, these features are in no way Non-SEO friendly. Some old tags like the frame tag are bad for SEO.

    Good riddance. None of these tags are used by modern webpages anyway.
